United States Patent 3,032,333 WORK HOLDER FOR OUTBOARD MOTORS Harold B.Fuller, 3601 Dartmouth Ave., Tampa, Fla. Filed Jan. 2, 1959, Ser. No.784,540 1 Claim. (Cl. 269-67) This invention relates to a work holderused to facilitate outboard motor repairs by supporting the work duringrepair.

In past years many outboard motor repair shops have been in need of awork holder to support outboard motor power head assemblies duringrepair. Until this time there has been no work holder adaptable tooutboard motor power head assembly repairs after the power head assemblyhas been removed from the support bracket on which it normally operates.An important object of this invention is to supply a means for thissupport while repairs are taking place.

Another object of this invention is to supply a means of rotating thepower head assembly on the supporting work holder to permit all sides ofthe assembly to be easily reached when required.

Another object of this invention is to make available a work holderwhich is easily portable and may be made ready for use by beingsupported by several different means.

Another important object of this invention is to supply a means ofchanging the work holder to permit repairs on many different shapes ofpower head assemblies and lock them in any of the 360 degrees ofrotation.

FIGURE 1 is a perspective of the work holder as mounted in a bench viseor other clamping device with the lower portion of the clamping devicebroken away.

FIGURE 2 is a side elevation of the work holder mounted on a work benchwith portion of the bench broken away and a typical power head assemblymounted on the work holder.

In this invention I provide a mounting block 5 which may be used in thejaws 8 of a clamping device or mounted on a work bench 13 by means ofthe bolts 12 passing through the holes 9 in the flanges 15 of themounting block.

Passing through the mounting block is a shaft 7 through which passes apin 6 at one end. The opposite end of the shaft is threaded to which isapplied the lock nut 2 and the mounting plate 1 which is also threaded.Next to the lock nut is placed a washer 3 and the spring 4 is compressedaround the shaft between the washer and the mounting block. To themounting plate is mounted the "ice power head assembly 16 by means ofthe bolts 11 passing through the holes 10 of the mounting plate.

When working on various power head assemblies it becomes necessary tochange the mounting plate to fit the d'fferent hole configurations. Themounting plate may be changed by turning the lock nut so it will moveaway from the plate. The plate is then free to rotate and be removed.The new plate is placed on the shaft by rotating and locked in place bymoving the lock nut toward the plate until it is tight. The plate mayalso be locked in any position in this manner.

It is also necessary to work on the power head assemblies at manydifferent angles. It is readily accomplished by means of rotation of theplate. Applying a force on the power head assembly and plate toward thepin compresses the spring and forces the pin out of the slots 14 andpermits the shaft to turn freely in the block. Rotation is stopped byremoving the force on the plate permitting the spring to expand and thepin to engage in several slOtS. The number of degrees of each stop maybe regulated by the number of slots placed on the back of the mountingblock into which the pin may engage.

In view of the above description I claim:

A work holder comprising a mounting block having front and rear parallelfaces, means on said mounting block for mounting the same on a support,a shaft rotatably mounted in a bore in said mounting block, the axis ofsaid bore extending perpendicular to the front and rear faces of themounting block and being centrally located with respect to said faces;the rear face of said mounting block having a plurality of angularlyrelated radially extending slots formed therein extending outwardly fromthe bore and in communication therewith for angularly positioning theshaft within the bore, a pin extending through one end portion of theshaft and adapted to be seated selectively in said slots, a mountingplate secured to the other end portion of the shaft and spring meansextending between the mounting plate and the front face of the mountingblock biasing the shaft in a direction to urge the pin to seat inpreselected slots.
